Abstract
Investigates the direct relationship between iron contamination of bisphenol A and its colour. Discusses the possibility of electrochemical migration of the metal impurity from installation material into reaction medium during the synthesis. Also suggests reducing the reaction time despite the less concentrated product obtained, especially since a better quality bisphenol A can be obtained.
